CHECK-CONTROLLED MECHANISM.

- Application filed August 10, 1926.

This invention relates to coin or check mechanisms, and particularly tosuch mechanisms as are associated with vending machines.

One objectof the invention is to provide a. mechanism, controlled by thedeposit of a coin or check, which will operate a detent shaft to move adisplay device, for the purpose of exposing articles in succession.

Another object is to provide means for preventing retrograde movement ofan operating rod, when forward movement has begun, and means forreleasing the iirst means upon completion of the forward movement of therod, whereby to permit the parts to resume normal position.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying Y drawings.

In the drawings:

Figure 1 is an elevation of the mechanism, in normal position, and witha coin in proper position for operating `the detent shaft.

Figure 2 is an elevation of thev parts when the operating rod has beenpulled out, and the detent shaft has been rocked.

Figure 3 is a horizontal sectional view on the line 3 3 of Figure 1.

Figure et is a vertical sectional view on the line 11-1 of Figure 1Referring particularly to the accompanying drawings, 10 represents abase through which is disposed one end of a shaft 11, which is adaptedto operate detente, not

means, such displaying means being illustinted in my Patent #1,556,541,issued October G, 1925, and in which patent is also shown the detents ofthe shaft 11.

Secured on said end of the shaft 11 isa radially extending arm 12, theouter end of which is provided with a nose 13, to which A brace 14 ismounted on the base, and secured at its opposite ends to the arm 12, andto the brace, is a coil spring 15, which normally urges the arm 12upwardly to rock the shaft 11 in such position that the detente willhold the display means against movement.

Pivotally mounted on the base, adjacent the nose of the arm l2, is arockable member 16, the upper portion of which is formed with a coin orcheck receiving notch or re- Selial No. 128,446.

cess 17, such recess opening in the direction of the said nose, wherebyto permit .the coin or check to engage with said nose. The upper end ofthe member 1G is formed with hook portion 18, overlying the adjacent endf Yupper end of the arm 21 there is connected an operating rod 23,having a terminal hand loop 24, which is adapted to be grasped .to

pull the rod, .and cause the rocking of the yarm 21. The upper edge ofthe link 2() is formed with ratchet teeth 25, which are .engaged by thebefore-mentioned pawl 19. A coil spring 26 is connected, at one end, tothe ratchet link 20, and at its other end to a bracket 27, secured tothe base 10, for the purpose of normally urging the link in onedirection, whereby to cause the hook of the member 16 to rock the pawl19 out of engagement with the teeth of the link.

Disposed in an inclined position on the upper portion of the base 10 isthe coin or check chute 28, the lower end of which is disposed inposition to deposit a coin or check in the notch of the member .16,while .the upper end is provided with coin or check receiving slot 29.The lower end of the chute is also disposed in close relation to thenose of the arm 12, whereby the coin orchecr is held within the notch orrecess, and partially resting against the said nose.

The pawl 19 .is normally spring pressed into engagement with the teethof the link 20.

Pivotally mounted on the base, inwardly of the lower end of the chute28, is an arcuate member 30, one end of which is provided with alaterally directed foot 31, normally engaged by the arm 12, to rock saidmember and press its other end, which isv provided with a similar foot3.., downwardly against the inner end of the pawl 19, whereby to rockthe pawl and maintain its nose out of engagement with the teeth 25. Thispermits the free outward movement of the link 20, when the lever 21 isswung outwardly, without accomplishing any operation of the parts of thedevice, should no coin be deposited in the machine.

Villien a coin is deposited in the upper end of the chute, such coinwill slide down the chute until it enters the notch of the member 16,and rests against the nose of the arm 12. Upon pulling outwardly on therod 23, the arm 21 will be rocked on its pivot, causing the link 2O tobe drawn therewith, which in turn causes the member 16 to be rocked,with the result that the coin or cheek moves the arm 12, to rock theshaft 11. As the shaft 11 is rocked, the arcuate member 30 is releasedfrom the arm 12, whereupon the spring 19 rocks the pawl so as to engageits nose with the teeth 25, and at the same time move the adjacent endof the arcuate member 30 upwardly until said member is stopped by thepin 10. llhen the link 20 has moved to the limit of its stroke, the coinwill have wiped pastthe nose of the arm 12 and fallen from the notch orrecess, into a box 33, disposed to receive it, whereupon the arm 12 isfree to be restored to normal position by its spring 15. When the arm 12has moved upwardly it engages with the foot 31, of the arcuate member,rocking said member so that its other foot 32 depresses the adjacent endof the pawl 19, and holds the nose of the latter elevated out ofengagement with the teeth of the link 20. The spring` 26 restores therod 23, the arm 21, and the rocker 16, to normal position, whereby thelatter presents its coin notch in position beneath the coin chute, toreceive a coin.

Attention is directed to the fact that, after having deposited a coin inthe chute, and such coin has passed into the recess of the member 1G, anoutward pull on the rod 23 causes the entire operation of the device,and the restoration of the arm 12, and the shaft 11, to normal position,without releasing the rod Upon releasing the rod 23, the remainder ofthe parts assume their normal Y position.

lWhat is clain'ied is:

.1. The combination with a shaft, of a check controlled operating meanstherefor including an arm on the shaft, a check receiving rockablemember, means for rocking the member to engage the check with said armto move said arm and rock said shaft, means for preventing` prematureretrograde movement of the rocking means, and means operable by the saidarm upon assuming normal position for releasing the preventing meansupon completion of the stroke of said rockable member.

2. The combination with a shaft having a radial arm thereon, a rockablemember having a recess for the reception of a check and arranged to berocked to engage the cheek with the arm to rock the arm and shaft, meansfor rocking the rockable member including a toothed member, a springurged detent normally out of engagement with the toothed member, a rockarm engaged at one end with the detent and having its other end engagedby said radial arm whereby to rock the detent out of engagement with thetoothed member and movable by said detent upon movement of said arm awaytherefrom. Y

3. The combination with a shaft having a radial arm thereon, of a checkcontrolled operating` mechanism for said arm and shaft including arockable member having a check receiving recess and arranged in positionto engage a check with said arm t0 move.

the latter and rock the shaft, an operating means connected with therockable member and including a toothed link, a detent nor* mally urgedtoward engagement with the the teeth of the link and normally held fromsuch engagement, and means disposed in position to be engaged and rockedby the said arm upon movement of the arm toward normal position todisengage the detent from the link, said last-named means being rockedin the opposite direction by the detent upon movement of said arm awayfrom Y said means.

4. The combination with a rock shaft having a radial arm thereon, of arockable member having a check receiving recess and disposed in positionto engage the check with said arm, an operating arm, a toothed linkoperatively connected with the operating arm and the rockable member,adetent for engagement with the toothed link, said detent being normallyout of engagement with the link, and an arcuate member having one enddisposed in the path of the said arm to be engaged and rocked therebyupon movement of the arm toward normal position, the other end of saidarcuate member being arranged to engage the said detent, to rock thesame out of engagement with the link upon such engagement by said arm.

In testimony whereof, I affix my signature.
